  • Davis, Duane L.; Stevenson, Jeffrey S.; Schmidt, W.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Gilts were artificially inseminated on the fifth, sixth and seventh days after estrous synchronization with altrenogest (scheduled AI). Contemporary controls also were synchronized but were checked for estrus twice daily. ...
  • Tonn, S.; Groothius, P.; Boese, B.; Blair, R.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    The problem of reduced reproductive performance in sows weaned at 5 to 11 days (early weaned) after farrowing was assessed by comparing estrous and embryonic traits in these sows and others weaned at 23 to 31 days ...
  • Lamb, G.C.; Miller, B.L.; Traffas, V.; Corah, L.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    In April, 1996, 1501 yearling crossbred heifers located on seven different ranches were estrus-synchronized and artificially inseminated (AI) 12 hours after they were detected in estrus. Herd size ranged from 82 to 43 ...
  • Kiracofe, G.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Several methods of synchronizing estrus have been tried in swine. One of the oldest and most commonly used natural methods is weaning pigs from a group of sows simultaneously. When this is done, the majority of sows will ...
  • Simms, D.D.; Sprott, L.R.; Odde, Kenneth G.; Corah, L.R. (Kansas State University. Agricultural Experiment Station, 1982)
    In 22 field trials involving 1,692 cattle, we evaluated Lutalyse as an estrus-synchronization agent for both natural mating and artificial insemination. Only 52.7% of the females in all 22 trials were cycling at the start ...
  • Larson, J.E.; Lamb, G.C.; Geary, T.W.; Stevenson, Jeffrey S.; Johnson, Sandra K.; Day, M.L.; Kesler, D.J.; DeJarnette, J.M.; Landblom, D.G.; Whittier, D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Our objectives were to determine whether a fixed-timed artificial insemination (TAI) protocol could yield similar fertility rates to a protocol requiring detection of estrus and whether an injection of gonadotropin ...
  • Larson, J.E.; Lamb, G.C.; Stevenson, Jeffrey S.; Marston, T.W.; Johnson, Sandra K.; Day, M.L.; Geary, T.W.; Kesler, D.J.; DeJarnette, J.M.; Schrick, F.N.; Areseneau, J.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Our objectives were to determine whether a fixed-time artificial insemination (TAI) protocol could yield pregnancy rates similar to a protocol requiring detection of estrus and whether inclusion of a CIDR (a vaginal insert ...
  • Smith, J.F.; VanBaale, M.; Jamison, C.; Rodriguez, R.; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    A project to evaluate the degree of heat stress in individual dairies was carried out in the summer of 2005. The object of this project was to develop a method to evaluate or audit how effective an individual dairy is in ...
  • Main, R.G.; Minton, J. Ernest; Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    We conducted two trials to evaluate the effects of feeding graded levels of cloves to weanling pigs as a substitute for antimicrobials. In the first trial, improvements in ADG were observed in pigs fed the lowest level ...
  • Whitham, N.G.; Coetzer, C.M.; Hunter, R.D.; Drouillard, James S.; Blasi, Dale A.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    A 99-day study was conducted to evaluate growth performance of 216 beef heifers (average 524 lb) fed traditional roughage-based diets at 2.75% of body weight or limit-fed highconcentrate diets containing corn or corn ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1989)
    A computer program was developed for analyzing DHI records to evaluate potential losses from 1) reproduction, 2) nutrition, 3) milk quality, and 4) genetics. Production-tested Kansas Holstein herds were grouped according ...
  • Neill, C.R.; Groesbeck, C.N.; Lawrence, K.R.; Hastad, C.W.; Gottlob, R.O.; Hildabrand, B.M.; Nelssen, Jim L.; Tokach, Michael D.; Goodband, Robert D.; DeRouchey, Joel M.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    A total of 224 nursery pigs (PIC L 327L × C22) initially 12.9 ± 3.0 lb and 21 d of age were used in a 28-d feeding trial. The objective of our study was to evaluate the effects of oregano oil, with or without an in-feed ...
  • Boyd, G.; Corah, L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Results from two trials showed that serving capacity (SC) can be successfully evaluated in yearling beef bulls under field conditions and is influenced by sire line (P<.01). Also, providing sexual experience to low ...
  • Gross, K.; Harmon, D.; Avery, T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1988)
    Two experiments were performed with mature wether lambs to evaluate availability of selected nutrients and volatile fatty acids for maintenance and growth. We used a technique in which known amounts of volatile fatty ...
  • Corah, L.; Kiracofe, G.; McKee, M.; Schalles, R.R. (Kansas State University. Agricultural Experiment Station, 1979)
    Two years of research with nine herds indicated one of two yearling bulls with a herd usually will sire most of the calves. In six of the nine cases, the bull we pre-evaluated as most sexually active was the sire of the ...
  • Corah, L.; Kiracofe, G.; Bridson, V.; McKee, M.; Schalles, R.R. (Kansas State University. Agricultural Experiment Station, 1978)
    Although this is based on only ones years’ results, it indicates that the breeding potential of yearling bulls can be determined before they are run with a cow herd. In this test one bull sired the majority of the calves ...
  • Baumann, Nicholas W.; West, A.; Phebus, Randall K. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2014)
    One of the key issues involved in accurately testing beef and the environment for the presence of specific bacteria, particularly pathogens such as Shiga toxin-producing Escherichia coli (STEC), is maintaining the viability ...
